In general, there is a wide range of applications requiring coupled electromagneticstructural analysis. In this paper, two of such coupled problems have been analyzed. The first one is a transient analysis of Electromagnetic Forming process and the other problem is a deformation analysis of a coil in a static electromagnetic field. These problems are simulated in COMSOL using AC/DC module and ...

A 3D electro-conjugate heat transfer model was made to study an embedded microfluidic/TEG system (μF/TEG) system. An innovative embedded microfluidic/TEG system (μF/TEG) system is proposed which enables a device to be able to provide power to its cooling system eliminating external power input and resulting in energy efficient and more reliable heat removal system. The research identifies ...

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...

Crystallization phenomena are of first interest in several industrial applications (polymer forming processes, metallurgy, phase change flow, energy storage...). A classical way to model the crystallization evolution is using the Nakamura kinetics law. In this paper, a novel physics interface is developed using the Physics Builder of COMSOL Multiphysics® , which accounts for the resolution of ...

This paper presents the modeling and simulation of electro-thermo-mechanical self-oscillators, an emerging type of M/NEMS-enabled timing devices in which sustaining electronic amplifiers are not required for their operation. Indeed, they realize amplification in the mechanical domain and feedback by crossing three physical domains: electrical, thermal and mechanical. In a previous work , we ...

Microcontact printing is a method for depositing patterns of thin films or molecular monolayers on surfaces using a polydimethylsiloxane (PDMS) stamp for selective mechanical contact (Figure 1). Undesired deformation of the stamp features during printing affects printed pattern quality. Hence, stamps need to be well-designed to prevent erroneous prints. Existing investigations identify the ...

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance (NMR). The HTS NMR system is inserted into the bore of an existing high field magnet. A compensating Helmholtz ...

The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics (including a boundary layer between the electrolyte and the electrode particles). During discharge, the ...

In The Netherlands rising dampness problems due to flooding of rivers and high groundwater levels form an essential treat for monumental buildings and heritage. A number of cases exists where rising dampness problems lead to the deterioration of wall finishes but also of valuable wall paintings in churches and castles. To explore the problem and to look for solutions like drying regimes, ...

In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only takes place in an electromagnetic boundary layer due to the skin effect and the force is confined within this ...
